Regenerative Energie
A full–scale co–fermentation facility processing 15,000 t of household and commercial organic waste as well as 41,000 t of municipal sewage sludge per year was studied focussing on the elimination of selected endocrine disrupting compounds.
In the course of the fermentation process the concentrations of the contraceptive pharmaceuticals 17á–ethynylestradiol and mestranol and of the natural steroid hormone estriol were below the limit of detection in all samples. The natural steroid hormone 17â-estradiol was detectable in all samples but in all but one cases the concentrations were below the limit of quantification. The concentration of estrone which is the primary metabolite of 17â-estradiol, ranged from 35.1 to 69.1 µg/kg dry matter (DM). The concentrations of 4-nonylphenol, 4-tert-octylphenol, and 4-nonylphenol monoethoxylate amounted to up to 3,180 µg/kg DM, 354 µg/kg DM, and 6,980 µg/kg DM, respectively. Surprisingly, bisphenol A (BPA) was detected in sanitised sludge derived from organic waste. The BPA concentration amounted to 662 µg/kg DM and, thus, was distinctly higher than in the mixture of primary sewage sludge and activated sewage sludge. The concentrations of all xenobiotic compounds (APX and BPA) distinctly increased during the 20 days of fermentation.

Rechtliche und praktische Unsicherheiten bei der Durchführung des europäischen Klimaanpassungsrechts durch das Bundes- Klimaanpassungsgesetz (KAnG)

In the context of the European Climate Law (EU) 2021/1119), the Governance Regulation (EU) 2018/1999 and the Nature Restoration Regulation (EU) 2024/1991, the KAnG came into force on July 1, 2024.
Transformatives Klimarecht: Raum, Zeit, Gesellschaft

This article contends that climate law should be conceived as inherently transformative in a double sense. The law not only guides the necessary transformation of economy and society, but is itself undergoing transformation.
